.NET Framework 4.8 is ... also included in Windows 11 so, as of October 2024, its lifecycle is currently dictated by the Windows 11 lifecycle.

That leads to the following questions:

1. Until when will Windows 11 be supported, and
2. Will Windows 12 support .NET Framework?

In the links below it is declared until when certain releases of Windows 11 will be supported, but not until when Windows 11 itself, i.e. its final release will be supported.
Windows 11 Home and Pro - Microsoft Lifecycle
Windows 11 Enterprise and Education - Microsoft Lifecycle
